Dear Lord... That's my point!
You think they had the same team developing AO Tennis in their spare time, while DBC 17 was being made as well as Rugby League Live as well as Ashes Cricket ???- All by the same people?!?!
There might be some cross over, but they would be run as three very seperate teams and neither should impact the development of the other except in extraordinary circumstances when people get pulled short notice to do internal testing, debugging, etc. Just because the AO mobile team is releasing patches doesn't mean BA have stopped all development on Ashes Cricket.
Just because AO Tennis is releasing next week doesn't mean that all the other devs are sitting around with their thumbs up their behinds. Perhaps they are on some well deserved leave over Christmas? Perhaps they have been pulled short term to make sure AO Tennis gets out the door on time, but it isn't going to have that detrimental effect on Ashes Cricket. Especially when you are concerned about a mobile app that is a completely unrelated to anything.
If anything, the same devs might be doing BBL mobile and AO Tennis mobile. So it might affect BBL IF anything. Not going to make diddlysquat difference to Ashes Cricket.
